Network Slicing Exploits

CRITICAL SEVERITY
Overview

Network slicing exploits target the 5G feature that creates multiple virtual networks on shared infrastructure, attempting to breach slice isolation or perform cross-slice attacks.

Technical Overview

5G network slicing uses virtualization and SDN to create isolated logical networks. Attacks target the slice isolation mechanisms, orchestration layer, or exploit misconfigurations to access resources from other slices or the underlying infrastructure.

Impact
Potential consequences of this attack

API Vulnerabilities

5G networks expose numerous APIs for network functions, edge computing, and third-party services. Vulnerabilities in these APIs can lead to unauthorized access, data breaches, and service disruption.

5G Attacks
Edge Computing Attacks

5G edge computing brings computation closer to users for low latency. Attacks target edge nodes, multi-tenancy isolation, or exploit the distributed nature of edge infrastructure.

5G Attacks
gNodeB Spoofing

gNodeB spoofing involves deploying fake 5G base stations that impersonate legitimate network infrastructure to intercept communications and perform man-in-the-middle attacks.
